Issues with WCAG 2.1's "2.4.7" to "2.4.10" Pages & Links

Hello,

In browsing through your site https://www.w3.org/TR/WCAG21/ we've noticed
that this primary WCAG 2.1 page lists the following:

   1. 2.4.7 as Focus Visible
   2. 2.4.8 as Location
   3. 2.4.9 as Link Purpose (Link Only)
   4. 2.4.10 as Section Headings

However, the WCAG's Understanding pages starting from 2.4.7 and going to
2.4.10 all appear to be improperly shifted because Focus Visible has been
misplaced from 2.4.7 and listed as 2.4.10, and the others in that range are
all shifted up by one place because of that.

Currently, this means that the Understanding pages show this:

   1. 2.4.7 Location – *should be Focus Visible*
   https://www.w3.org/WAI/WCAG21/Understanding/location
   2. 2.4.8 Link Purpose (Link Only) – *should be Location*
   https://www.w3.org/WAI/WCAG21/Understanding/link-purpose-link-only
   3. 2.4.9 Section Headings – *should be Link Purpose (Link Only)*
   https://www.w3.org/WAI/WCAG21/Understanding/section-headings
   4. 2.4.10: Focus Visible Enhanced – *should be Section Headings*
   https://www.w3.org/WAI/WCAG21/Understanding/focus-visible-enhanced

This causes a number of issues ranging from completely broken links, to
misdirecting cross-references, to improper anchor tags on all of those 5
URLs I've provided.

I wasn't sure of what the best location to reach out to with this
information would be, but I'm hoping that this site comments e-mail address
might be able to help address these concerns, or pass it along to reach
someone who might be able to correct those issues. If there's anywhere else
I should e-mail this information to directly instead, please advise.

Best regards,
